Something that's funny: Since I knew exactly this time what I was getting myself into, I was so prepared mentally that I don't feel especially tired or exhausted (I mean, after two good nights of sleep).

I already started reading in "The Shellcoder's Handbook" yesterday. I am starting to study for OSCE tonight (first pass watching the videos).

BTW, I also stopped working on OSCE two years ago because after CISSP, I was totally brain dead. I --HATED-- studying for this exam!! I almost burn myself out. I ended up taking almost a full year off after CISSP...
